A method for preventing soil fracture and/or monitoring borehole pressure
during jet grouting that may include monitoring borehole pressure at one
or more points in a jet grouting borehole while the jet grouting is being
performed and determining whether the borehole pressure exceeds a
predetermined limit. The method may further include providing
notification to a jet grouting operator that there is a high risk of soil
fracture if the borehole pressure exceeds the predetermined limit. The
predetermined limit may be the estimated fracture pressure of the soil in
which the jet grouting is being performed.
